Jaqui and I have a similar specialty and I leverage it in my consultancy to reduce license costs for the clients.
The challenge I face, as I bet a fair number of you do, is even in 2010, many of the people I work for don't have the vaguest idea about what goes in to business class I.T. Their philosophy is, "It's a computer so you should know what to do...and it shouldn't take more that a couple of mouse clicks to do it because that's all computer work is." In their minds, we're just hoarding a bag of tricks that we won't share with them.
I recently told two clients a contractor would need to be called for cabling. Both of them thought that should be part of my job and one of them quite vigorously told me so. I told him I'd gladly help him get one. I already know two that do excellent work.
Understanding that we're experts in some things but not all is what I consider necessary humility but in the minds of these clients it contributes to my incompetence.
Where do I rate myself? If I didn't know I was good at what I did I wouldn't do it. Some of my clients would call me an expert. Some might not even call me novice. I have found the technical part of running the business to be the easiest part by far.
